Mycloud keeps falling off the network

I am having the same problem, SMB 1 enabled, connected through a switch (even though prompted by WD support I also tried a direct router (Netgear Orbi) connection, same difference). The thing is accessible for a few minutes up to an hour or so after a power-cycle (no other way to reboot), then no dashboard (“Connection refused”), no ssh (just hangs there), no file access, no cloud access, nothing. All three LEDs are solid blue, lots of network traffic on the NIC LED.

Here are some more, similar experiences. Maybe one of the suggestions works for you. They did not for me.
